Hi,
I am having problems with calling a lambda function with a persisted state.
Here the lambda function:
val satVapPressure = [ GenericItem argTemp |
var temp = (argTemp.state as QuantityType<Temperature>).toBigDecimal
0.6108*Math.exp(17.27*temp/(temp+237.3))
]
Calling the function with
logInfo("Button Test Button", "Result satVapPressure {}", satVapPressure.apply(Wetterinformationen_Aussentemperatur))
works fine, however, if I want to do the same with a persisted state
var meanSatVapPressure = satVapPressure.apply(Wetterinformationen_Aussentemperatur.averageSince(now.minusHours(24)) as GenericItem)
logInfo("Button Test Button", "mean Saturation Vapour Pressure {}", meanSatVapPressure)
doesn’t work and gives mit the following log
2025-05-02 00:00:43.784 [ERROR] [.handler.AbstractScriptModuleHandler] - Script execution of rule with UID 'irrigation-1' failed: Could not cast 16.69001355682870 °C to org.openhab.core.items.GenericItem; line 30, column 47, length 84 in irrigation
Using other casts like Number or NumberItem doesn’t work either.
If I log the persisted state without calling the lambda function there is no problem.
Would be great if anyone could point out what I am doing wrong here.
Many thanks
